sudo modprobe -r brcmfmac && sudo modprobe brcmfmac also works for me on my mac book pro running xenial mate edition.
Another note that if the laptop goes to sleep and wakes it may lose the network interface. It appears as 'auto ethernet' when it's not functioning properly. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1577113 Title: 50/50 chance for BCM43602 to come up correctly during boot Status in linux package in Ubuntu: Incomplete Bug description: My BCM43602 has a 50/50 chance during boot of ever becoming "ready" and pulling an IP address. The problem seems to be this "link is not ready" and "already exists" loop. The log I sent was one of the cases where things eventually worked. If I get unlucky, it simply repeats the "already exists" / "not ready" loop indefinitely. I get a similar situation when suspending/resuming. I've already pulled the firmware and stuck it under /lib (see dmesg output for version).
